A magnet system for an outwardly opening magnet valve having a core winding, an armature carrying the valve body, and a permanent magnet disposed symmetrically to the winding. The closed magnet circuits of the electromagnet and permanent magnet partly overlap, and a ring of ferromagnetic material is associated with the permanent magnet 1 in the magnet circuit of the electromagnet, this ring absorbs half the flux I of the permanent magnet, and the magnet circuit for the electromagnet is dimensioned to one-half the permanent flux.
